Heck, if the deer are not running more than 20 yards, I'd say the bullets are working just fine. I've killed lots of pigs with Sierra's 85gr BTHP.
^^^This. I have had great luck with the 85gr GameKings in my 6x45 on deer and pigs. I use the 95gr Nosler BTs and 100gr Sierra ProHunters in my 243, also with great results.
I like a good blood trail as much as anyone; but if an animal goes 20 yards or less before dying, it is really a non-issue... The bullet has done its job.
